Randomized Controlled Trial
Inconsistency between simultaneous blood pressure measurements in the arm, forearm, and leg in anesthetized children.
To determine the accuracy and precision of simultaneous noninvasive blood pressure (NIBP) measurement in the arm, forearm, and ankle in anesthetized children. ⋯ Forearm and ankle NIBP measurements are unreliable and inconsistent with NIBP measured in the arm of anesthetized children. These alternative BP measurement sites are not reliable in accuracy (comparison with reference "gold" standard) and precision (reproducibility).

Angelman syndrome arises by one of 4 genetic mechanisms. Patients often have craniofacial abnormalities, vagal hypertonia, skeletal muscle atrophy or underdevelopment, a history of seizure disorders, and pharmacodynamic unpredictability. Its pathogenesis, clinical manifestations, diagnosis and treatment options, and perioperative anesthetic considerations are presented.

Evidence supports the concept that patients undergoing major orthopedic surgery benefit from either thromboprophylaxis or peripheral nerve blocks, especially continuous techniques. A group of anesthesiologists with significant experience in orthopedic anesthesia and peripheral nerve blocks reviewed the literature related to thromboprophylaxis and peripheral nerve blocks and their combination in orthopedics. Major bleeding, including retroperitoneal hematoma, is an established complication of thromboprophylaxis. ⋯ Between 1997 and 2012, only 4 case reports of major bleeding were reported in patients receiving thromboprophylaxis and peripheral nerve blocks. Evidence supports the safety of the combination of thromboprophylaxis and peripheral nerve blocks. This group of experts concluded that currently there is no evidence that the combination of thromboprophylaxis and peripheral nerve block increases the risk of major bleeding compared to either of the treatments alone.

To determine whether postoperative epidural analgesia is associated with better recurrence-free survival and overall survival after lung cancer surgery. ⋯ The type of postoperative analgesia used after surgery for nonsmall cell lung cancer is not associated with better 2-year or 5-year recurrence-free survival or overall survival rates.

A case of tension pneumopericardium that occurred after total gastrectomy in an 80 year old woman is presented. There have been some prior case reports of pneumopericardium that occurred during positive pressure ventilation; in this patient hypotension due to tension pneumopericardium occurred after extubation. Return of spontaneous ventilation with negative-pressure breathing may have induced air aspiration into the pericardial sac from the abdominal cavity.
